If true, the whitespace of the submitted string value will be stripped
via the trim() function when the data is bound. This guarantees that
if a value is submitted with extra whitespace, it will be removed before
the value is merged back onto the underlying object.

If true, any errors for this field will be passed to the parent field
or form. For example, if set to true on a normal field, any errors for
that field will be attached to the main form, not to the specific field.
